You can find the Calculation Summary on both the Circuit Details Page as well as the M-IDAP Page. First review all warnings and errors shown here an [verify the errors and warnings on the CML History tab](/v414/docs/m-idap-errors-and-warning).

Make sure IMS Calculated is unchecked. Only MIDAP and Time-Based should be checked.

There is a [horserace](/v414/docs/miro-horserace) between the M-IDAP and Time-Based NID. The soonest NID will win and will be applied to the Circuit.

The Calc Summary must be calculated and **Final Approved**. This way the Schedule is credited, and a new [Corrosion Schedule](/v414/docs/defining-corrosion-schedules) is created with the new [NID](/v414/docs/miro-horserace).

To calculate the data:

- Click the calculate button to calculate the NID.

To Approve the Calc Summary:

- Click the Approve button to open the Approve section.![Graphical user interface, application  Description automatically generated](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/calculating-and-approving-the-calc-summary-image-4qfvmygh.png?sv=2026-02-06&spr=https&st=2026-10-28T14%3A18%3A53Z&se=2026-10-28T15%3A18%3A53Z&sr=c&sp=r&sig=LS2891ZYnctGXwOpCJHwm4%2Fp63Dfgd9QwodPxjmNTAY%3D)Click the Approve button.
- Click **Approve** to Final Approve the Calc Summary. Note: This creates an inspection event for the MSET.

- The Corrosion Schedule of the Circuit will be credited and a new NID will be set. Also, if the Circuit is inherited to an RBI Component, the Calc Summary will automatically be applied in the [RBI Analysis **Inspection History** tab](/v414/docs/software-step-5), to update the RBI LID.
